Protector for boots and shoes



Aug. 4 1942. .1. T. JOOSTEN PROTECTOR FOR hoows AND SHOES Filed 'Jan. 15. 194i Patented Aug. 4, 1942 PROTECTOR FOR BOOTS AND SHOES Johannes Theodorus Joosten, Arnhem, Netherlands Application January 15, 1941, Serial No. 374,552 In the Netherlands December 28, 1939 (C1. Eli-59) 2 Claims.

The invention relates to a protector for boots and shoes, the sole portion of which consists of a plurality of strips, extending throughout the entire width of the sole.

The invention has for its object an improvement in a protector for boots and shoes of this known type and consists in this that the sole strips as well as the heel protector are made of cast metal and at the exterior surface are each provided with a plurality of knob-shaped projections which are integral with the protecting appliance.

This has the advantage of a relatively slight wear and of ductility, whereby the protector is less liable to rupture. Moreover the knob-shaped projections will under no circumstances press through the protector and the leather directly against the foot since the pressure is always uniformly distributed over the entire width of the sole.

The material may, e. g., be Temperguss or another light metal alloy.

According to the invention the sole-protector preferably comprises three strips, the rearmost of which have two longitudinal edges which are curved in such a manner that the strips are narrower centrally than at the lateral edges.

Due to this embodiment of the strips a certain flexibility of the entire sole is maintained, which would otherwise be mainly lost if the strips were of equal width and would engage one another throughout the entire length.

Finally according to the invention the heelprotector is formed by a circumferential strip enlarged at the inner rear side to two symmetrical inclined portions and having at the inner front side two attachment lugs located, at the sole side, on one and the same plane with the strip but having a smaller thickness than the strip itself.

This construction in the first place offers a resistance against the known wearing down at the side of the heels. Secondly the embedded location of the attachment lugs enables to obtain a satisfactory attachment of the heel protector. It is namely possible to arrange within the strip an extreme layer of leather, covering said lugs and having an outer surface flush with the outer surface of the strip.

The invention and its various features will now be explained more fully with reference to the drawing, illustrating an embodiment of the protector by way of example.

Fig. 1 is a bottom view of a shoe provided with protecting means.

Fig. 2 is a section of said protecting means on the line II-II in Fig. 1.

Fig. 3 is a section on the line 1II-III in Fig. 1.

Against the sole I three protecting pieces 2, 3 and 4 are attached by means of embedded tacks for which the holes are denoted by 5. Against the heel a protecting piece I is applied. The shape of the sole protecting strips follows from the drawing. As appears therefrom, the strips 3 and 4 are narrower centrally than at the lateral edges; the longitudinal edges of these strips are curved. By this particular shaping they permit a sufficient flexing of the sole which contributes to an easy walking.

All of the strips have knob-shaped projections B, the shape of which appears from Fig. 2. These projections are integral with the strip itself, that is provided therewith.

The heel protector 1 consists of a strip that at the rounded rear side is enlarged inwardly by inclined or oblique portions 9. Besides by tacks, to be inserted into the holes 5, this protector is attached to the heel also by means of two attachment lugs II], which have also tack holes H. The space within the heel protector is filled up by a leather disc [2 (see Fig. 3). The attachment lugs it) are thinner than the protector itself so that they are concealed by the heel leather.

The oblique enlargements 9 afford the desired resistance against wearing down at the side of the heels.

I claim:

1. A sole having a multipart sole protector thereon comprising a plurality of spaced strips extending across the entire width of the sole, said strips having curved longitudinal edges transversely to the longitudinal axis of the sole and being provided at the tread surface with a plurality of knob-like projections integral therewith, said strips being made of cast metal and the edges of said strips extending along the boundaries of the sole having a thickness greater than the thickness of said strips but less than the thickness of said projections and being provided with apertures for attaching means.

2. A sole having a multipart sole protector thereon comprising a plurality of spaced strips extending across the entire width of the sole, said strips having curved longitudinal edges transversely to the longitudinal axis of the sole and being provided at the tread surface with a plurality of knob-like projections integral therewith, said strips being made of cast metal, a plurality of the rearniost strips having their longitudinal edges curved in such a manner that such strips are narrower in the middle than at the ends, the rearmost strip having its longitudinal edges curved with opposite concave curvatures, the edges of said strips extending along the boundaries of the sole having a thickness greater than the thickness of said strips but less than the thickness of said projections and being provided with apertures for attaching means and said strips covering a major portion of said sole.
